DRIP CUP AND SELF OILING ATTACHMENT FOR BEARINGS SPECIFICATION formingpart of Letters Patent No. 335,840, dated February 9, 1886.

Application filed December 31, 1885. Serial No. 187,248.

To all whom it may concern:

Be it known that I, ANTONIO O. PESSANO, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Drip-Cups and SelfOilingAttachments for Bearings, which improvement is fully set forth in thefollowing specification and accompanying drawings, in which Figure 1represents a vertical section of a drip-cup and self oiling attachmentfor bearings embodying my invention. Fig. 2 represents a horizontalsection thereof in line :r m, Fig. 1.

Similar letters of reference indicate corresponding parts in the twofigures.

My invention consists of a drip cup adapted lo prevent waste oil fromescaping along shafting and being thrown into the apartment where theshafting is located, and also serves as a feed-cup, as will behereinafter set forth.

Referring to the drawings, A represents a vertical shaft, and B thebearing thereof.

represents a drip-cup, which freely encircles the shaft below thebearing B, and is secured to the latter by a screw, E, it being noticedthat the cupis of the form of a segment of a circle in cross-section,leaving a month or opening, 0, on the inner face at the upper partitionthereof, or on the side toward the shaft.

Fixed to the shaft A is a collar or deflector, D, which is located belowthe bearing B, and overhangs the lower wall, 0 of the mouth 0.

In lieu of the screw Efor connecting the cup with the bearing, the cupand bearing maybe cast together.

The cup is provided with screws or plugs F G, respectively fordischarging and replenishing purposes.

It will be seen that when the shaft is in operation the waste oiltherefrom reaching the collar D is forced by centrifugal action into thecup 0, where it is collected, and thus pre- 45 vented from escaping intothe apartment.

(No model.)

In order to adapt the drip-cup as a feedcup, I employ a piece, H, ofwick, felt, or other absorbent material, and run the same through agroove or duct, J, on the inner face of the bearing and in contact withthe shaft, the lower end of the material being located in the oil in thedrip-cup, so that by capillary attraction said oil is fed to thebearing, and so lubricate's the shaft.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

- 1. A drip-cup encirclingashaftand adapted to collect waste oil fromsaid shaft,su bslantiall y as described.

2. A drip-cup encircling a shaft below the bearing thereof and providedwith a month on the side toward the shaft, so as to collect the wasteoil therefrom, substantially as de scribed.

3. A collar connected with a rotary shaft, in combination with adrip-cup which encircles said shaft, the collar being located adj-a centto the mouth ofthe drip-cup, so as to di rect waste oil from the shaftinto the cup. sub stantially as described. I

4. A drip-cup, in combination with a collar which is fixed to a rotaryshaft and pro jects into said cup, substantially as described.

5. A shalt provided with adrip-cup, in combination with a bearing havinga groove on its inner face, and a piece of absorbent material, wherebythe shaft is lubricated, substantially as described. I

(3. A shaft provided with a drip-cup of the form of a segment of acircle in cross-section. leaving a mouth or inlet on the side toward theshaft, and containing a piece of absorbent material, which is passed tothe shaft, forming a combined drip cup and feed, substantially asdescribed.
